Description and Uses

Dimethylamine hydrochloride is the raw material of organic synthesis, the catalyzer of analysis as an acetylize, and the preparation of azoviolet and dimethylamine aqueous solution. Dimethylamine hydrochloride deoxidation is very capable, and corrodibility is vital, so be usually used in cleaning-type soldering flux. Preparation technology is for slowly splashing into hydrochloric acid in dimethylamine for tradition, and the speed that splashes into is no more than 15 ℃ with temperature, and pH=7-8 is limited. After the reaction finishes, activated carbon decolorizing is added, the filtrate is adjusted to pH=3-4 with hydrochloric acid, decompression is steamed water to the greatest extent, obtaining dimethylamine hydrochloride.

Dimethylamine hydrochloride is used as an intermediate in the manufacture of pharmaceuticals like ranitidine and metformin, tramadol and amlodipine. It is used as a precursor of atrazine. It is associated with sodium acetate and used to carry out the Willgerodt- Kindler reaction to prepare amides. Its free base reacts with carbon disulfide to get dimethyldithiocarbamate which is used in rubber vulcanization. It is involved in the synthesis of dimethyl-(1-methyl-pyrrol-2-ylmethyl)-amine by reacting with 1-methyl pyrrole and formaldehyde.
